The water plan rules affect the storage and discharge of your dairy effluent

The rules in the ORC Regional Plan: Water have been updated, which means in most cases consent will now be needed for both effluent storage facilities and discharging effluent to land.

Depending on the set-up of the system, and what you are proposing to do, further consents may be necessary (e.g., components of an effluent system: weeping wall, stone trap, sump).

The rules apply now for new and existing animal waste storage. 

All new ponds and tanks will generally require resource consent before they are constructed. Some smaller structures that are not used for storage will not need consent. As well as consent for your storage, you will also need consent to discharge effluent to land.

Existing effluent storage constructed prior to 25 March 2020 that does not meet the permitted criteria is temporarily permitted with an application for consent not needing to be lodged until at least 4 June 2023 or until a later date for some systems. However, farmers are encouraged to apply now or to start thinking about their storage system.
